Installation Instructions Part 1

G-Series Installation & Commissioning 50
4.9 SeaTalk & Alarm connection
The alarm output and SeaTalk are combined into a single connec-
tor. This includes a 12 V fused power supply.
Alarm output
The alarm output is used to alert the operator to alarms and other
audible warnings.
Note: Alarms are global and as such will be sounded across all
audio and alarm outputs across the system.
SeaTalk connection
The SeaTalk connection allows the G-Series system to receive
data from Raymarine SeaTalk compatible devices such as:
• Autopilot
The G-Series can receive and display autopilot information and
act as a repeat controller. Refer to the separate reference guide
for operation details.
• Instruments
The G-Series can receive and display data received from instru-
ments, such as wind, speed and depth.
• GPS
Required for chart applications.
Master GPM
The SeaTalk bus must be connected to the Master GPM (see
page 37).
Note: SeaTalk connection to other GPMs for the purposes of
redundancy is allowed.
12 V power supply
The SeaTalk connection provides a 12 V supply rated at 125 mA.
This is suitable to supply 1 sounder module.
Note: SeaTalk instruments will usually be powered from a sepa-
rate power supply, e.g from a Raymarine autopilot course
computer. You should not power a SeaTalk bus from more
than one supply.
